INVOLVEMENT OF ADRENERGIC SYSTEMS OF THE BRAIN IN CONDITIONED REFLEX ACTIVITY

Among the problems of biology and medicine, the system of regulation of adaptation processes with the help of neuropeptides is one of the most pressing. An excessive reaction to stress is a prerequisite for the occurrence of various diseases. This is due to the transformation of the adaptive response into a separate stressor event (Meyerson, 1984). Functional changes in the central nervous system under the influence of extreme environmental factors are characterized by changes in metabolism, disruption of energy processes occurring in the brain, as well as accelerated aging and cell death. Shifts in the neuropeptide regulation system lead to disruption of homeostasis and, possibly, “aging” of organs and tissues, i.e. changes in the ratio of homeostatic and behavioral reactions. In recent years, neuropeptides with anti-stress properties have attracted the attention of researchers as the most promising in terms of inhibiting age-related changes in the central nervous system.
